Killzone: Shadow Fall will ship with a $20 season pass, Sony has announced.

Developer Guerrilla Games is planning “several forms” of downloadable content for “extensive post-launch multiplayer support.” Competitive multiplayer maps will be released for free, as well as paid expansion packs that promise to “further enhance” the shooter’s online experience.

The $20 season pass will include the following expansion packs as they become available:

Online co-op expansion pack – focusing on team play and intense combat, the online co-op expansion pack adds a new co-operative game mode in which you and up to three online friends must survive against impossible odds. Fight waves upon waves of enemies in four new arena maps, featuring a unique leveling system and new unlocks.

Three online co-op map packs – each map pack consists of two brand-new arena maps you can play in co-op mode with your friends. Please note that these arena maps will only work with the online co-op expansion pack.
